For instance, simple statements such as “g radiation would pass straight through” or “the foils stops alpha particles” were both rewarded. The idea that the ty of beta particles p rating through aluminium foil depends on its thickness was often poorly expressed, although a minority of ...
Identify any point which is anomalous (unexpected). Decide whether a straight line of best fit or a curved line of best fit is appropriate and draw it on your graph. Leave blank (7) (iii) Use your graph to predict the value of y when x is 20°. 下载文档 收藏 分享 赏 0...
Straight Line直线图方程:y = mx+c m 是图形的梯度(斜率)slope; c是y轴截距(直线与y轴交点); x和y是变量,水平线的方程为y=c(因为梯度为0); 垂直线的方程为x=d (因为d是与x轴相交的地方)。 02 距离-时间图 距离-时间图显示垂直(y)轴上的距离和水平(x)轴上的时间。距离-时间图上直线的梯度就是...
line due to a perpendicular force • Recognise that if there is no resultant (F = mv2/ r is not required) force on a body it either remains at rest or continues at constant speed in a straight line • Understand friction as the force between two surfaces which impedes motion and ...
(c) A bus is travelling along a straight road. The bus and the driver have a combined mass of 16000kg when there are no passengers in it. The bus has 73 passengers. The average mass of each of the passengers is 65kg. (i) Calculate the total mass of the bus, the driver and the...
